-----------------------------------------------------------------
Shalin - do you see the existing replication handler mechanism becoming cloud
aware or do you see replication changing all together, for example from
periodically polling a master for index changes (which ain't real-time), to
being implemented as real-time synchronous or asynchronous per-document,
push-based replication a la ElasticSearch?
If we look towards the bottom of http://wiki.apache.org/solr/NewSolrCloudDesign
there is even a mention of replication functionality (in its today's form) not
being needed any more once Solr Cloud functionality is all in place. If that
is correct, what is the plan for this issue?
